- •
We assess genetic diversity in eight lines of banana shrimp selected for length over 14 generations.
- •
Loss of genetic diversity was consistent over lines, generations, and ways to measure variation.
- •
With multiple lines net genetic variation of the wild founders can largely be maintained over lines.
- •
By crossing among lines, genetic variability can be restored.
